[Resolved] why visitors cannot download media files

Hello,
I just uploaded few files for the visitors of the site.
But it seems that only admin can access them.
When a norma visitor tries to access my process engg. related files they get following message:
“Sorry, no posts matched your criteria.”

I’ve not made any major changes in configuration settings as such.
I tried to look whether there’s permission or access configuration options available, but it’s not there… or is it there but I missed it?

Actually I had to ‘insert the media files’ instead I typed url. & it worked. I shouldn’t have been that way. but thats the way it is, you have to insert a media file and then you’ll get option of posting ‘link file’ or ‘link post’ If you select former file will start downloading directly. & for the latter you’ll see file description page.
